How the Energy Independence and Security Act (EISA) Shapes Your Electric Motor Strategy
In December 2010, the Energy Independence and Security Act (EISA) of 2007 took effect, mandating that motor manufacturers meet NEMA Premium efficiency standards for all motors rated under 600 V. This rule change expands the scope of EPAct‑compliant motors, affecting a wide range of applications.
Below is a quick reference to the motor categories that were previously exempt but are now required to meet the new efficiency criteria:
- 8‑pole motors
- Close‑coupled pump motors
- Design‑C motors
- U‑frame motors
- Three‑phase motors ≤ 600 V (excluding 230 V or 460 V) and IEC‑frame motors from 90 frame and larger
- C‑face or D‑flange motors without a base
- 201‑to‑500 HP motors not covered by EPAct, now required to meet NEMA MG 1, Table 12‑11 energy‑efficient ratings
- Vertical solid‑shaft normal‑thrust motors (P‑base) tested in a horizontal configuration
